Abstract

SE TRATA DE UN SISTEMA DE FILTRADO CERRADO PARA SEPARAR RAPIDA Y EFICIENTEMENTE GLOBULOS ROJOS DE GLOBULOS BLANCOS. EL SISTEMA COMPRENDE, AL MENOS, DOS BOLSAS DE SANGRE EN COMUNICACION CERRADA ENTRE UNA Y OTRA POR MEDIO DE UN FILTRO INTERMEDIO QUE COMPRENDE UN ALOJAMIENTO QUE CONTIENE FIBRA DE FILTRADO CONTINUA. EL ALOJAMIENTO PREFERENTEMENTE TERMINA EN PUNTA Y LA FIBRA PREFERENTEMENTE TIENE UN AREA DE SECCION DE CORTE CON FORMA DE Y Y SE ADAPTA PARA PERMITIR LA SEPARACION SUSTANCIAL DE LOS GLOBULOS BLANCOS DE LOS GLOBULOS ROJOS, CON UNA MINIMA HEMOLISIS DE LOS GLOBULOS ROJOS CUANDO LA MEZCLA SE DILUYE CON UNA SOLUCION CONSERVANTE Y SE PASA DE UNA BOLSA HACIA LA OTRA EN UN FLUJO RELATIVAMENTE ALTO. LA FILTRACION SE COMPLETA DENTRO DE LAS 24 HORAS, PREFERIBLEMENTE EN LAS 6 HORAS SIGUIENTES A LA DONACION DE LA SANGRE.
